Free Dynamic DNS Service

Azrael is a dynamic DNS service provider. Azrael offers free accounts to anyone. Each account can have up to 25 hosts with dynamically assigned IPv4 addresses. Azrael provides an update API to allow for easy and quick host updates. The API mimics the dyndns2 protocol so that many common DDNS update clients will work with it. It has been known to work with ddclient, DD-WRT, Tomato USB, Open-WRT, Curl, and most other DDNS clients.
